Book Description
El deterioro obvio de los ambientes acuáticos, tanto dulces (ríos, lagos y embalses) como costeros (lagunas, estuarios, bahías, marismas), es resultado de los cambios provocados por las diversas actividades antropogénicas, teniendo como consecuencia que la calidad del agua que sostiene a una gran variedad de organismos se haya visto alterada en diverso grado. Bajo este panorama algunos organismos acuáticos pueden resistir adaptándose a condiciones deletereas definiendo así al ambiente, u otros desaparecer por no soportar condiciones de impacto. De esta manera surge la necesidad de proponer aquellos organismos que caractericen condiciones particulares, para ser usados como indicadores de la calidad del agua, como una herramienta incluso, para generalizarse en el monitoreo del preciado líquido.

La presente obra es una aportación primigenia que comprendía bibliográficamente aquella información nacional de fitoplancton, algas, peces, crustáceos, moluscos, insectos y parásitos con posibilidades de ser usados como indicadores (bioindicadores) de la calidad del agua. Estos grupos, presentados como capítulos, contienen nombres científicos de los organismos, en ciertos casos el vulgar, sus características morfológicas junto con una figura o fotografía para identificación en campo, su hábitat, su distribución nacional o regional y a qué tipo de ambiente caracteriza. En esta obra se podrán observar los primeros esfuerzos de rescatar material informativo de diversas fuentes para proponer a los interesados aquellos elementos biológicos que aún podemos disponer para la evaluación ambiental: con el temor de que algunos otros ya hayan desaparecido por el impacto ambiental.

Water Resources in Mexico
Author: Úrsula Oswald Spring
Publisher: Springer Science & Business Media
ISBN: 3642054323
Category : Science
Languages : en
Pages : 535
Book Description
Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.

Microbial Biodiversity, Biotechnology and Ecosystem Sustainability
Author: Cristóbal Noé Aguilar
Publisher: Springer Nature
ISBN: 9811943362
Category : Science
Languages : en
Pages : 529
Book Description
This book gives insight into several aspects of the microbiology, biotechnology, and ecosystem sustainability of special and under-explored regions, that captivate human beings by their natural richness, their extensive biodiversity, the extraordinary forms of adaptation of the living beings that they inhabit, and even that keep living secrets as is the very origin of life. The chapters emphasize all aspects of biological diversity-its description, analysis, and conservation, and its controlled rational use by humankind. Also, the book is elaborated from a wide and multidisciplinary point of view. It presents reviews, research papers, comments, and research notes on biodiversity, ethnobiology, geoscience, chemistry, biological conservation, biotechnology, and ecosystem sustainability Two hotspots are the reference for this enriching book that describes details of extraordinary areas of the planet, from Cuatrociénegas, Coahuila (Mexico) to the Southern Western Ghats (India). The book will contribute to dealing with the practicalities of conservation management, economic, social, and political issues. It provides a forum for examining conflicts between sustainable development and human dependence on biodiversity in agriculture, environmental management, and biotechnology, and encourages contributions from developing countries to promote broad global perspectives on matters of biodiversity and conservation.

Freshwater Fishes of North America
Author: Melvin L. Warren Jr.
Publisher: JHU Press
ISBN: 1421435136
Category : Science
Languages : en
Pages : 934
Book Description
The highly anticipated second volume of Freshwater Fishes of North America, a monumental, fully illustrated reference that provides comprehensive details on the freshwater fishes of the United States, Canada, and Mexico. When the first volume of Freshwater Fishes of North America was published, it was immediately hailed as the definitive reference in the field. Readers have been fervently awaiting the next volume in this encompassing three-book set ever since. Now complete, volume 2, covering families Characidae to Poeciliidae, is the result of decades of analysis by leading fish experts from universities and research laboratories across North America. Each volume in this authoritative synthesis covers the ecology, morphology, reproduction, distribution, behavior, taxonomy, conservation, and the fossil record of the included North American fish families. The encyclopedic reviews of each family are accompanied by color photographs (nearly 250 in this volume alone), range maps, and artwork created by noted fish illustrator Joseph R. Tomelleri. The result is a rich textual and visual experience that covers everything known about the diversity, natural history, ecology, and biology of North American freshwater fishes. Volume 2 covers the following North American families of fishes: Characidae (Characins) Ictaluridae (North American Catfishes) Ariidae (Sea Catfishes) Heptapteridae (Three-barbeled Catfishes) Osmeridae (Smelts) Esociformes (Esocidae, Pikes and Umbridae, Mudminnows) Percopsidae (Trout-perches) Amblyopsidae (Cavefishes) Aphredoderidae (Pirate Perches) Gadidae (Cods and Cuskfishes) Mugilidae (Mullets) Atherinopsidae (New World Silversides) Beloniformes (Needlefishes and Halfbeaks) Rivulidae (New World Rivulines) Profundulidae (Middle American Killifishes) Goodeidae (Goodeids) Fundulidae (Topminnows) Cyprinodontidae (Pupfishes) Poeciliidae (Livebearers) The chapter authors of Volume 2 are: Gianetta Adams Clyde Barbour Micah Bennett Ricardo Bentancur-R.

Plankton Ecology of the Southwestern Atlantic
Author: Mónica S. Hoffmeyer
Publisher: Springer
ISBN: 3319778692
Category : Science
Languages : en
Pages : 592
Book Description
This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts
